Rockville BluTube SG 70W Bluetooth Tube Amplifier/Home Theater Receiver

Purchased this tube amp about 2 years ago and it has worked very well for me. Great sound quality, everything works properly including the fiber, coax, USB and BT. It has plenty of power to drive big speakers and has been totally reliable. I had a 1959 HK tube amp and wow did it sound good, but I had to rebuild it every few years. I finally sold it and got this little one. If you want to try a tube amp, I recommend this one. Not too expensive and it has all the functionality that you need for digital music too.

Sounds good in ratio to the cost. This is a quality amp. It is not a few thousand dollar tube amp. It does all it should and sounds good. I would buy again. I am not replacing a McIntosh amp with this.

I replaced a little bear preamp with this in my system. I hooked up my powered sub to the BluTube and then hooked up the speakers to the BluTube instead of the powered subwoofer and what a difference I hear. The USB works great, the phono playback is wonderful and very tubey. The bluetooth connection is perfect. What a sonic difference this provides for my vinyl. UPDATE! The more I use this the more I love it! The tubes are certainly in the mix. Turn on the turntable, drop the needle and then turn on the amp. You will not hear any sound until the tubes begin to warm up and of course the sound increases as they get warmer. What a wonderful looking and sounding change to what I had before. As for the meter on the amp, this measures the intensity of sound from your into the amp, phono is low, cd is much stronger. There is no defect in the meter.

Sounds great if you don't use the sub out. I have been trying many alternatives for the las 10 months!! There is a droning 60hz hum that happens on the sub side. Not an issue with the desktop speakers, only with my Polk 12" powered sub (which has been used for 10+ years with no issue). Tried different cables, tried grounding equipment externally, nothing helps. Seems some sort of internal grounding is causing an issue.

Purchased the Rockville tube amplifier with the sub out option. It was well packaged and easy to set up. Had it up and running in about 10 minutes with bt connectivity and playing music. Have a small cd player connected to the auxiliary out and Klipsch 2.5 speakers with a new Monoprice subwoofer. Very very impressive what you can do with $149.00 amp and some stuff laying around. The Rockville is amazing for the money. Will it give you the Mark Levinson/Thiel speaker combo sound? Nope. But for what it cost I am thoroughly impressed and very satisfied. Excellent value. Well built and nice sound. Honesty, blown away by the amazing sound for the $$ spent.

I initiall bought this to just connect between turntable and my Klipsch tower speakers. Setup was easy and I'm basically able to use it like a receiver. I also have a Playstation console and PC connected to so I can channel audio from different sources to this amplifier. Flicking the front switch let's me switch between turntable, TV (Playstation and PC) and Bluetooth audio sources. Now the sound from this amplifier is crisp clear and sounds great, no complains. I'm amazed how good it makes my records sounds. Sound from other sources sounds great too. Asthetically, it's a perfect blend of modern and vintage, I love it. I also love how the orange lighting matches the target light on turntable and complements the copper color of my speakers. I'm very happy with this purchase and highly recommend this amplifier.

The sound quality is amazing from this tube amp as long as you're driving the Auxiliary input or the HDMI/Optical/Coax. I feed it with a hifi DAC so the SNR and THD are inaudible to me. Flip it over to Bluetooth and you have an audible hum coming from the speakers when there is nothing playing. Can't notice it during quiet sections of music much, but it is there. VU meter is sluggish but works. I put 1 star for remote control because my unit did not come with a remote. Should it have? It has all analog control knobs... It would be cool if they were motorized but I highly doubt it. Driving Klipsch R-280f Floor Stand Speakers, it can get plenty loud - enough to feel the bass in your chest without any distortion. For reference I listen to mostly rock, alternative, metal, and some pop when the kids are around. The EQ is touchy and can add more bass or treble than you'd ever need. I prefer neutral sound, but the bass knob can give plenty of kick at +2 (-10 to +10 range). Any more sounds extremely muddy to my ears, but some may prefer the extra boost for smaller/less sensitive speakers. My speakers tend to run harsh on the treble side so the treble is perfect at 0. I am overall happy with my purchase since the bluetooth will only be used by my wife/kids who don't notice the hum nor care enough anyways. There's an ambiance to the unit too that just looks cool in my shop. The glowing tubes and VU meter look classy from a distance. Fit and Finish isn't bad either. From less than two feet away you can see some of the cheaper material choices and design elements that are slightly janky near the tubes but it's all forgivable once the speakers are bumping and I'm getting stuff done.

So I bought this 5 years ago mostly for the headphone amp. I've always thought it was great for that. Today I was setting up a new television with a couple Elac Debut 2.0 B5.2 and a Bic F sub with my Sony STRDH 190 Receiver. Well the Sony sounded clean but lacked something. I swapped it out with the Rockville and the difference was wonderful. Even just watching an Amazon series the sound was so much warmer and richer. I'm not knowledgeable enough to know if this could be down to the Rockville having an optical input which the Sony lacks but I kind of doubt it. Rockville gas me impressed! Needless to say, I will be using the Rockville in this little setup! I only wish it had a remote!! If it had a remote it would be perfect!

Bon système de son se Rockville tube, très bonne qualité sonar, je l'utilise avec une Télévision Android et avec le Téléphone ou la tablette Android, en me servent du Bluetooth ! Ça joue la musique avec qualité audio HiFi !

En términos generales bien aún no noto la diferencia por la parte preamplificada de los tubos porque no es puramente de tubos si no tiene dos pases la pre con los tubos y la amplificada que es digital. No encuentro tubos para hacerle un uograde a algunos de mejor calidad y con ello mejorar el sonido. Lo tengo conectado a dos bocinas Kenwood y un subwoofer pero quiero una klipsh de alta eficiencia mínimo 90db de sencibilidad. Lo uso con una salida óptica doble una a la PC y otra a la pantalla y la verdad ni llegó a la mitad del volumen para un espacio de 10 o 15 mts cuadrados le compré garantía extendida pues la marca no es muy conocida. 16/01/2021 Antes que nada todo ha funcionado perfectamente USB permite reproducir todos los formatos incluso de alta calidad como FLAC sin problema solo que no tienes mucho control si tienes varias carpetas ya que reproduce de una forma lineal. Le hice upgrade a unas bocinas Klipsch y son la pareja perfecta los tubos originales se usaron por más de 20 horas permitiendo que se quemen en su totalidad y se asienten muy complacido por la calidad de audio y potencia. El día de hoy llegaron unos reemplazos de tubos que la única opción que encontré de mejor calidad fue en un sitio de Inglaterra fue algo laborioso investigar que opciones de tubo se podrían reemplazar ya que las nomenclaturas de los tubos chinos no son idénticas a las de otros países. Aquí quiero resaltar que SI se puede haber upgrade de manera segura sabiendo que reemplazo puede llevar. Los tubos que reemplazo son: Pequeños la sección preamplificador 6N1P Pares comprobados y equivalentes modelo 1968 grado militar ruso alta duración igual más de 5 mil horas, con un raro contenido mineral para mejorar los harmonicos. La misma aleación de nikel platino para los pines y oro en las rejillas. Más amortiguadores anti vibración estos son los aros plásticos que se ven en las imágenes. Estoy cambiando a 5 estrellas porque superó mis expectativas Largos o de potencia 6P1P-EV Fueron rusos de grado militar con un tiempo de uso largo estimado en más de 5000 horas con pines de nikel platinado con rejillas de oro Los encontré en Inglaterra y tardaron casi dos meses en llegar pero lo valen. 22/06/2023 Estoy muy satisfecho con el equipo funciona de maravilla, le puse unas bocinas Klipsch mas eficientes y hace un mes compre un tornamesa Audio Technica el cual lo conecte y funciona de maravilla, solo noto que el nivel de volumen al que escucho los vinilos es mas alto que lo que envio por via optica en FLAC de 24 bits y 192000 Khz

Por el precio es bueno. Pero deberían traer bulbos de refacción o incluir paquete de bulbos de mejor calidad.

Arrived on time was very easy to setup and sound great.

For my first tube amp this thing for the money sounds just as good as my Harmon Kardon
